OSCOR Blue (OBL-24) – Spectrum analyzer

The application of communication systems in various sectors is rapidly developing worldwide, especially mobile and satellite systems, which use wideband communication channels. OSCOR Blue is a serious tool for the evaluation and integration of these systems in the radio frequency range.

OSCOR Blue can be successfully used for:

• Detection of unauthorized signals in a very crowded radio frequency spectrum.
• Analysis of radio frequency signal distribution
• Evaluation of communication channel utilization
• Determination of communication system coverage area (cell towers, radio relay systems)
• Installation and maintenance of wireless data transmission systems

The application of communication systems in various sectors is rapidly developing worldwide, especially mobile and satellite systems, which use wideband communication channels. OSCOR Blue is a serious tool for the evaluation and integration of these systems in the radio frequency range.

Analysis and distribution of the radio frequency spectrum is of great importance for many organizations, such as wireless operators, airports, ports, laboratories, and during design and exploration work. OSCOR Blue is an excellent tool for detecting “complex” radio frequency signals in adverse environments.

Range/Operating Speed

OSCOR Blue scans the 24 GHz range in 1 second with a step of 12.2 kHz. High scanning speed, built-in antennas, embedded software, and quick readiness for operation allow for significant time saving when working with OSCOR Blue.

Automatic Multi-Antenna System Switch

• The use of the built-in automatic antenna system switch allows obtaining a real-time image in the range from 10 kHz to 24 GHz (10 kHz to 8 GHz for model OBL – 8) without “stitching” and “dead zones”.
• The built-in 10 dB preamplifier increases receiver sensitivity.
• The built-in attenuator from 0 to -30 dB allows operation near powerful transmitters.
• Capturing and detecting all active signals. There are no losses due to limited antenna range or the need to switch external antennas.

Compactness

Light weight (up to 4 kg) and small dimensions allow the OSCOR Blue to be used mobilely for data collection and signal analysis in the field. Built-in antennas and software allow the device to be easily deployed to capture and compare the signal spectrum in various locations.

Patented Trace Analysis for Fast Signal Detection

In addition to its compact size, high speed, and mobility, the trace analysis function developed by REI adds the possibility for a complete analysis of the signal spectrum on the device screen without the need for an additional computer. The functionalities of the trace analysis software and the user-friendly menu navigation of the OSCOR Blue allow for high productivity.

Creating a Signal List

Based on the trace analysis, a signal list is created according to peak values. Furthermore, signal lists can be created for different locations with subsequent comparison of these lists.

• Creation of a signal list from trace analysis according to the corresponding algorithm
• Multiple creation of a signal list, at one pass per second
• Analysis of unstable signals (with packet transmission, with changing frequency).

Sonogram

Viewing a raster spectrogram (sonogram) obtained from trace analysis over a period of time.

Dynamic Display of Persistent Signal Spectrogram

Dynamic display of the persistent signal spectrogram allows detection of the active signal spectrum in a complex radio frequency environment, using dynamic color change to visually separate the signal from ambient noise or numerous transient signals.

Transient (non-repeating) signals are displayed in darker colors (blue and green) and fade quickly, while persistent signals are displayed in bright colors (red and yellow). This allows for easy identification of persistent signals in the presence of interference.

Detailed “Waterfall” Spectrogram Recording

• Allows recording detailed information about signal spectra over a long period of time, exceeding 30 hours, and then analyzing it in detail.
• Recording and viewing the spectrogram allows detecting the activity of transmitters with frequency hopping (FHSS), pulsed, and many others.
• OSCOR Blue allows recording a “Waterfall” spectrogram with a minimum resolution of 12.2 kHz (every 5 seconds minimum)
